Include Version Info from Git into Info.plist at build time

gistfile1.txt

Add the script include-version-info.sh into a new run script build phase of your application target. The build phase 
should be located after the build phase "Copy Bundle Resources".

include-version-info.sh

# Use Xcode's copy of the Git binary
GIT=`xcrun -find git`

# Use the commit count as CFBundleVersion
GIT_COMMIT_COUNT=`${GIT} rev-list --count HEAD`
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion ${GIT_COMMIT_COUNT}" "${BUILT_PRODUCTS_DIR}/${INFOPLIST_PATH}"

## Use the last annotated tag as CFBundleShortVersionString
GIT_TAG=`${GIT} describe --tags --always --dirty`
/usr/libexec/PlistBuddy -c "Set :CFBundleShortVersionString ${GIT_TAG}" "${BUILT_PRODUCTS_DIR}/${INFOPLIST_PATH}"

I had to remove this script temporarily as Xcode 11 GM Seed 2 (and everything before that) was clearing out the CFBundleVersion. I wasn't able to run my build on Jenkins as a result. It kept complaining about a missing bundle version even though it has a default value set that gets updated on the fly from this script. If anyone finds a workaround, I'd love to put this back.

Anyone find a fix for this? using xcrun agvtool next-version -all was working for me in a build phase run script, but then when I added a Xcode server Bot everything just breaks for some reason.

@billburgess I guess that the updates for the default value on the fly actually interferes with the (strange) logic of Xcode. I, too, wanted to have the version params to be saved in a text file (I tried xcconfig), but this didn't work reliably.

In the end, this script works for me when I put in Info.plist placeholders, like

<key>CFBundleShortVersionString</key>
<string>--</string>
<key>CFBundleVersion</key>
<string>--</string>
